To all 'whom/t may` concern.: g a N.; DAVIS, a

citizen of the United States, residing at Lodi,

in the county of Columbia andjStateofWisconsin, have invented `new anduseulim-A provements inRailroadfTies, of which the road ties, constructedof angle i. steel with` a filing of cement; `and it has for-lits objects to provide a tie of this class which shall possess superior advantages in point of simplicity, durability and general efficiency..

With these and other ends in viewwhch will readily appear as the nature of the in.

vention is better understood, the same consists 1n the improved constructlonand novel arrangement and combination ofgparts which will be 'hereinafter fully described and particularly pointed out inthe claims. Y f

In the accompanying, drawing has' been illustrated a simple and 'preferred form of thel invention; it being,VV however, understood that no limitation is necessarily madeto` the preciseV structural` details therein, exhibited', but that changes, alterations and modifications within theV scope of the`- vention may be resorted to when desired'.` f e In thedrawing, Figure 1 is a top plan view of a railroad tie constructed in accordance with the invention, but with thefnlling applied to one end only. Fig.,2 is ai'lon'gitudi-` nal sectional viewtaken Von the'plane indiev cated by the line 2-2` in Fig. 1. Fig. 3 yisa transverse sectional view taken onV the plane indicated by the line 3 3 lin Fig. 1.

Corresponding parts in the several figures,

are denoted by like characters of reference; The body oi the improved railroad tie' is composed of two angleplates Aff-A,fprefer ably of steel, each of said `plates `comprising a` vertical body portion 1` provided at its upper and lower edges with oppositelyextending iianges 2-3; theupper flanges` being extended outward from thebody of the tie, and

the lower flanges .being extended inwardly, toward each other.' The plates A-A are properly spaced apart by'sleeves 4 of ap-k proximately rectangular cross-section; said sleeves beingformed ofstrips of sheet metal,I bent in the proper shape, and vhavingjover-l lapping ends -whichgareplaced downingsupported upon the lower flanges l3;?" oi the body plates aswillbeclearly seen'in Fig. 3.

the spacing sleeves, which latter will thus be rmly connected with thebody plates.

. After placing the body plates, properly connected and spaced. apart, infposition, pref,-

erably upon thegrjoadbed, the tie is filled with a plastic'composition containing cement in suitable proportion, said composition, which is generically vknown as concrete, being permitted to settle and harden. It will be understoodthat the ties may be sunk beneath `thesurface of the road bed, so that the surrounding dirt will assist in 'forming a mold for theconcrete; `by thus sinking or embedding the ties ,subsequent ballasting may also be to Vsome extent avoided.

. "Before-the vapplication ofthe iilling, each of the spacing sleeves is provided with two vertically disposed bolts 7, the threaded ends Vof which project upward a suitable distance,

and said bolts being suitably spaced apart to admit the rail flange `between them. Rail supporting plates 8 are provided with apertures 9 to engage the bolts 7, and said plates rovided with terminal notches 10 forming` ugs 11 which are bent beneath the upper flanges 2k ofV the body members of the tie, upon which the su porting plates will thus tact with the s acing sleeves. The rails, one of Vwhich is s `own at 12, are then placed in position, ysaid rails being secured in posi- I tion by means of cli s 13 and nuts 14 applied t eir destination will be comparatively Abeiirrnly secured, irectly above and in cony An important `advantage of the small. The improvedties maybe very readilyfassembledjand placed in position.; and ward, the lapped portionsfo the sleevesfbehenrproperly made they will be practically 1. railroad tie comprising body plates having flanges at their upper and lower edges, spacing sleeves having overlapping ends supported upon the lower flanges, connecting bolts, and a filling of plastic inaterial.

2. A railroad tie comprising body plates having oppositely extending ilanges at their upper and lower edges, spacing sleeves interposed between the plates and having overlap ed ends, pairs of bolts extending vertica ly through the spacing sleeves, connecting bolts extending through the body plates and the'spacing sleeves, and rail supporting plates engaging the vertical bolts and having downturned lugs engaging the upper flanges of the body plates.

3. A railroad tie comprising body plates having oppositely extending :flanges at their upper and lower edges, spacing sleeves interosed between the plates and having overapped ends supported upon the lower iianges, pairs of bolts extending vertically through the spacing sleeves, connecting bolts extending horizontally through the sleeves and the body plates, a iilling of plastic ina terial, and rail supporting plates engaging the vertical bolts and having downturned lugs engaging the upper flanges o'l the body plates.

In testimony whereof I allx niy signature in presence of two witnesses.
